STEVAL-C34KAT2 Multisensing Expansion Kit

STMicroelectronics' STEVAL-C34KAT2 is a multisensing expansion kit with the STEVAL-C34AT02 expansion board and a flex cable. The ISM330IS sensor is soldered at the center of the small 25 mm x 25 mm board. The STTS22H temperature sensor is placed on the PCB side and is thermally coupled to the PCB bottom exposed pad through vias.

The ISM330IS is a system-in-package featuring a 3-axis digital accelerometer and a 3-axis digital gyroscope, boosting performance at 0.59 mA in high-performance mode and enabling always-on low-power features for optimal motion results in industrial and IoT solutions.

The ISM330IS embeds a new ST category of processing, the ISPU (intelligent sensor processing unit), to support real-time applications that rely on sensor data. The ISPU is an ultra-low-power, high-performance programmable core capable of real-time execution of AI algorithms, allowing state-of-the-art functionality in any wireless sensor node, from small equipment or accessories to enterprise solutions for anomaly detection, asset tracking, and factory automation.

The expansion board can be mounted on the equipment for the vibration analysis using four holes or double-sided adhesive tape. This board is compatible with the STWIN.box kit (STEVAL-STWINBX1 ).
